This is a variant of the WillTravel large format cameras (4x5, 5x7, 4x10 or 8x10) with a M65 focus helicoid and not the rotating frontcap in the basic design.
This design requires that you know the lens Flange Focal Distance (FFD) with a mm precision, as there are limited possibly for adjustments of the camera height. This also means that each body is tied to a specific lens as the FFDs varies much between lenses of the same nominal focal length. The bodies are designed 2mm shorter than the lens FFD, to ensure infinity focus. Then you may use shims to ensure that the M65 Helicoid end stop matches infinity. This is optional and not needed if you accept a bit overshoot on infinity focus.
As a start its only a 4x5 90mm and 135mm, 5x7 in 120mm available. Ask me and I will publish more.
In the commonspart zip you will find M65 lensboards and various shims.
For the rest of the parts like grip, groundglass and filmholder frame use the standard WillTravel parts for your camera format.
